Abstract

(57) [Summary] (Modified) [Purpose] To improve the handle of a conventional replaceable blade type hand saw. [Structure] Circular and elliptical eye nail holes 8 and 9 are provided at positions corresponding to the circular hole 6 and the oblong hole 7 provided substantially on the center line of the hollow portion 3, and only the oblong eye nail hole is provided. It is characterized in that the extension line is provided so as to be inclined so as to intersect with the center line.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a handle of a replaceable blade type hand saw whose mounting angle can be freely adjusted.

[0002]

[Prior art]

 The handle of the conventional hand-held saw is one in which the saw blade is fixed to the handle by inserting a nail into a nail hole that slightly penetrates the handle and the dent. However, in recent years, many replaceable hand-operated saws have been put on the market that can be replaced with new ones each time the saw blade becomes less sharp. Among these, for example, there is a structure in which a metal having a taper-shaped holder and a collar is incorporated in the saw handle and the saw blade is inserted into the saw handle (Shokai Sho 63-93101), or a saw handle. There is a structure (embedded Sho 63-93102) in which a metal fitting with an insertion part is embedded in the upper part and a replacement blade is combined in this, but all of them have complicated structures intended only for replacement, so they are not practical. However, it was not possible to adjust the mounting angle of the spare blade.

[Problems to be solved by the device]

 The present invention has been made in view of this point, and aims to provide a handle of a replaceable blade-type hand-operated saw that allows an operator to arbitrarily adjust the installation angle of the replaceable blade according to the wood quality and the sharpness of the material for sawing. It is a thing.

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention is an improvement of the conventional saw handle so that each of the holes of the saw handle sandwiching a dent portion provided with a circular hole and an oblong hole at approximately the center line. It is proposed to provide circular and oblong eye-shaped nail holes at positions corresponding to the above, and only the elliptic eye-shaped eye nail holes are provided so as to be inclined so that their extension lines intersect the center line.

The present invention will now be described with reference to the drawings. The handle 1 of the replaceable blade type hand saw according to the present invention has the appearance shown in FIG. 1, for example, and the dent portion 3 of the saw blade 2 is inserted into the insertion groove 4, The dent portion is fixed with a nail 5 penetrating the handle 1 and the dent portion 3. A circular hole 6 and a long elliptical hole 7 are provided in the recess 3 at substantially the center line in the longitudinal direction thereof with a space therebetween.

The shape of the handle of the present invention is not limited to that shown in the drawings, and is arbitrary. The handle of the present invention has an eyelet hole 8 and an oblong hole 9 corresponding to the oblong hole 7 and the circular hole 6 of the dent portion 3 of the saw blade 2. The oblong hole 9 has an extension line. It is installed at an angle that intersects the center line of the dent. If the saw blade is inserted into these holes and the saw blade is fixed to the handle, the replacement blade can be replaced easily, and if the position of the eye nail 5 in the oblong hole 7 is shifted, the eye nail penetrating the circular hole will be centered. In addition, the saw blade can be adjusted and fixed at any angle within the range of the length and inclination of the oblong hole.

In the present invention, the saw blade can be changed to the most suitable angle for work by loosening the tightening of the oval-shaped eye nails. For example, when the wood to be cut by sawing is thick, the angle is 45 °. By adjusting the angle to a smaller value as it becomes thinner, you can always work in a comfortable position, and you can freely change the saw blade. The oblong hole may have a diameter and a width that allow the eye nail to pass therethrough, and the length thereof is preferably determined in relation to the angle adjustment range.
